“…In addition, the results from some studies have indicated that exposure to magnetic field may be associated with the increased risk of adverse birth outcomes such as low birth weight [16] and miscarriages [17]. Some studies, however, did not find a statistically significant increased risk of preterm birth and low birth weight in relation to exposure to electromagnetic field during pregnancy [18,19] reproductive outcomes [14]. Pregnant women in Iran sometimes live very close to very high voltage overhead power lines and are exposed to electromagnetic fields [11].…”

Aim. The issue of preterm birth due to exposure to magnetic fields from power lines is unclear. Exposure to electromagnetic field in uterus has been hypothesized as possible preterm birth. The aim of the present study was to determine whether living closer to high voltage power lines increased the risk of preterm labor.Methods. In a nested case-control study, 135 cases of singleton live spontaneous preterm birth in Rohani hospital, Babol, Iran, during the period between 2013 and 2014 were studied. The 150 control subjects were singleton term live birth in the same year of birth and city of residence using randomized-digit dialing. The shortest distance to any of the high voltage power lines to the maternal residence during pregnancy was measured using ArcGIS software for every case and control. To test the association between the preterm births and the residential proximity to power lines, stepwise multiple logistic regression was used.Results. There were 28 households, 20 cases (14.8%) and 8 controls (5.3%) situated within 600 meters of high voltage power lines. The adjusted OR for spontaneous preterm birth and birth defect in women who were living in less than 600 meters from high voltage power lines was higher compared to those living at farther distance (OR = 3.28, CI: 1.37 to 7.85) and (OR = 5.05, CI: 1.52 to 16.78), respectively.Conclusions. Therefore, installing overhead power lines and stations within 600 meters or making overhead underground would be useful in the prevention of both preterm birth and birth defect.

“…Environmental factors such as extremely low frequency (ELF) electromagnetic fields have not been evaluated, despite evidence of an association with miscarriage,2–5 a related mortality outcome especially at early gestational ages when it is typically difficult to differentiate stillbirth from miscarriage. Although ELF field exposure does not appear to be associated with preterm birth and low birth weight,3 6 ELF fields could potentially operate through mechanisms influencing in utero mortality, including miscarriage and stillbirth, especially if fetal defects are involved. In light of lack of data, we evaluated the likelihood of stillbirth mortality from residential proximity to power transmission lines (a proxy for ELF field exposure) using population-based data.…”

“…In addition to cancer, some epidemiological studies have suggested that ELF-MF exposure is associated with an increased risk of other diseases, including neurodegenerative diseases, cardiovascular diseases, and adverse pregnancy outcomes [4–7]. However, other epidemiological studies have indicated a lack of any association [8–10], and laboratory studies have not provided consistent evidence supporting the epidemiological observations of associated increased disease risk [11, 12]. Generally, the biological effects induced by low-intensity ELF-MFs have not been determined, and the potential underlying mechanisms remain unclear.…”

Epidemiological studies have indicated a possible association between extremely low–frequency magnetic field (ELF-MF) exposure and the risk of nervous system diseases. However, laboratory studies have not provided consistent results for clarifying this association, despite many years of studies. In this study, we have systematically investigated the effects of 50 Hz MF exposure on DNA damage and cellular functions in both neurogenic tumor cell lines (U251, A172, SH-SY5Y) and primary cultured neurogenic cells from rats (astrocytes, microglia, cortical neurons). The results showed that exposure to a 50 Hz MF at 2.0 mT for up to 24 h did not influence γH2AX foci formation (an early marker of DNA double-strand breaks) in any of six different neurogenic cells. Exposure to a 50 Hz MF did not affect cell cycle progression, cell proliferation or cell viability in neurogenic tumor U251, A172 or SH-SY5Y cells. Furthermore, the MF exposure for 24 h did not significantly affect the secretion of cytokines (TNF-α, IL-6 or IL-1β) in astrocytes or microglia, or the phagocytic activity of microglia. In addition, MF exposure for 1 h per day did not significantly influence expression levels of microtubule-associated protein tau, microtubule-associated protein 2, postsynaptic density 95 or gephyrin in cortical neurons, indicating an absence of effects of MF exposure on the development of cortical neurons. In conclusion, our data suggest that exposure to a 50 Hz MF at 2.0 mT did not elicit DNA damage effects or abnormal cellular functions in the neurogenic cells studied.
